I was afraid of that, to some extent. Though if we disconnect the HDTV box's tuner, and patch in the vintage TV's tuner instead, it might trick the HDTV box into decoding a signal.. However, the HDTV box's tuner is digitally synthezized tuned, and the decoder may want to automatic fine tune the tuner to get the pilot frequency within some limits. An old style tube TV tuner would likely drift too much. So this concept is probably not gonna fly.
Now if the decoder wants some other IF freq, then that's the end of this ballgame.
